Subject: [PATCH] emacs: add nativeComp passthru

As reported by @terlar in
https://github.com/NixOS/nixpkgs/pull/235859#issuecomment-1597012885
the removal of nativeComp in passthru breaks external tooling.

This adds back `passthru.nativeComp` with a deprecation notice which sets the removal for 23.11.

(cherry picked from commit 75650d79da6c841ae27cd4b1392a11d74b117c26)
